Recording device and control method of recording device

Abstract

A recording device including a head configured to discharge an ink of ultraviolet curing type, an irradiation unit configured to irradiate a medium with an ultraviolet ray, a carriage mounted with the head and the irradiation unit, a movement mechanism configured to perform a forward operation in which the carriage is moved in a first direction and a return operation in which the carriage is moved in a second direction opposite to the first direction, and a control unit configured to control the movement mechanism and the irradiation unit, in which the control unit causes the head to execute discharge of the ink in the forward operation, and causes at least the irradiation unit to execute irradiation in the return operation, and makes a moving speed of the carriage in the return operation higher than a moving speed of the carriage in the forward operation.

What is claimed is: 
     
         1 . A recording device comprising:
 a head configured to discharge an ink of ultraviolet curing type toward a medium;   an irradiation unit configured to irradiate the medium with an ultraviolet ray;   a carriage mounted with the head and the irradiation unit;   a movement mechanism configured to move the carriage relative to the medium; and   a control unit configured to control the movement mechanism and the irradiation unit, wherein   the movement mechanism executes a forward operation of moving the carriage in a first direction with respect to the medium and a return operation of moving the carriage in a second direction opposite to the first direction with respect to the medium, and   the control unit   causes the head to execute discharge of the ink while causing the carriage to move in the forward operation, and causes at least the irradiation unit to execute irradiation while causing the carriage to move in the return operation, and   makes a moving speed of the carriage in the return operation higher than a moving speed of the carriage in the forward operation.   
     
     
         2 . The recording device according to  claim 1 , further comprising:
 a support base having a support surface that supports the medium, wherein   the support surface has a recess,   the carriage causes the head and the irradiation unit to face the support surface and holds the head and the irradiation unit, and   the carriage moves stepping over the recess of the support surface when moving in the first direction and the second direction.   
     
     
         3 . The recording device according to  claim 2 , wherein the support base includes a plurality of members, and the recess of the support surface is a joint of the members. 
     
     
         4 . The recording device according to  claim 1 , wherein the control unit operates the movement mechanism such that a maximum speed of the carriage in the return operation is higher than a maximum speed of the carriage in the forward operation. 
     
     
         5 . The recording device according to  claim 4 , wherein the control unit operates the movement mechanism such that a maximum speed of the carriage in the return operation is twice or more a maximum speed of the carriage in the forward operation. 
     
     
         6 . The recording device according to  claim 1 , wherein the return operation includes an acceleration period for accelerating the carriage by the movement mechanism, a constant speed period for moving the carriage at a constant speed, and a deceleration period for decelerating the carriage, and the constant speed period is 1/100 or less of an entirety of the return operation. 
     
     
         7 . The recording device according to  claim 1 , wherein the control unit causes the head to execute discharge of the ink and the irradiation unit to execute irradiation in the forward operation, and causes the irradiation unit to execute irradiation while moving the carriage at a return path speed in the return operation. 
     
     
         8 . The recording device according to  claim 7 , wherein the control unit makes an irradiation intensity of the irradiation unit in the return operation higher than an irradiation intensity of the irradiation unit in the forward operation. 
     
     
         9 . A control method of a recording device including a head configured to discharge an ink of ultraviolet curing type toward a medium, an irradiation unit configured to irradiate the medium with an ultraviolet ray, a carriage mounted with the head and the irradiation unit, and a movement mechanism configured to move the carriage relative to the medium, the control method comprising:
 executing, by the movement mechanism, a forward operation of moving the carriage in a first direction with respect to the medium and a return operation of moving the carriage in a second direction opposite to the first direction with respect to the medium;   causing the head to execute discharge of the ink while causing the carriage to move in the forward operation, and causing at least the irradiation unit to execute irradiation while causing the carriage to move in the return operation; and   making a moving speed of the carriage in the return operation higher than a moving speed of the carriage in the forward operation.
